That graph looks pretty good, but the story is a little different...
Full disclosure, I was given a free BTC robot license by the owners. I had PMed them because everything looked sketchy, so I told them I'd try it out to see if it was legit. I figured it wasn't legit and they wouldn't take me up on my offer, but they did. It does seem to be a legit company, but I'm just not a fan of how things are done.
They are really only looking at profit in terms of USD, and that graph makes it look like I gained a fair amount. Over the course of a month I actually lost BTC. I started with 2 BTC a month ago and when I withdrew the other day it was 1.965 and about $1 in the btc-e account. If you're looking to grow the amount of BTC you have I would suggest not using this.
Please let me know if there are any questions.
